Commands using sort from sorted by
Terminal - Commands using sort - 660 results
sort -t"," -n -k5 file.csv # according to the 5th field NUMERICALLY!!
ps -eo pmem,pid,comm --no-headers | sort -k1 -rn | head -10

Functions: head ps sort

Pros: the format is very simple, there is no need to show every columns, and full command with args

the first column is memory consumption %

the second column is pid

the third is just the command (without full arguments, most application's arguments are too long)

You can decide which application to kill then.

find . -maxdepth 1 -type d | grep -Pv "^.$" | sort -rn --field-separator="-" | sed -n '3,$p' | xargs rm -rf
yum whatprovides /usr/lib/libXX1.so /usr/lib/libXX2.so | grep fc | sed 's/^\(.*\)-[0-9.]*-.*$/\1/' | sort | uniq | xargs yum -y install

Functions: fc grep sed sort uniq xargs

this command will install the packages which provides the libraries you need to link with, e.g. when you compile something needs opengl libraries:

gcc -o testgl testgl.c -lGLEW -lGL -lGLU -lglut

you can use `/usr/lib/libGLEW.so /usr/lib/libGL.so /usr/lib/libGLU.so /usr/lib/libglut.so'

find . -type f | awk -F'.' '{print $NF}' | sort| uniq -c | sort -g

Works on current directory, with built-in sorting.

find . -type f -name '*.pm' -printf '%6s %p\n' | sort -nr | head -n 50

Functions: find head sort

Will work with filenames with spaces inside. Will not break in case of someone making directory that matches *.pm. And sorts from largest. Where largest is file size, not line count.

vzlist -a -H -o hostname,diskspace,diskspace.s,veid | awk '{ printf( "%2.f%\t%s\t%s\n"), $2*100/$3, $4, $1}' | sort -r

"sort_csn" is a function to sort a comma separated list of numbers.

Define the the function with this:

sort_csn () { echo "${1}" | sed -e "s/,/\n/g"| sort -nu | awk '{printf("%s,",$0)} END {printf("\n")}' | sed -e "s/,$//"; }

Use the function like this:

sort_csn 443,22,80,8200,1533,21,1723,1352,25


One example where this is useful is when port scanning with nmap and getting a list of open ports in random order. If you use Nessus, you may need to create a scan policy for that set of specific ports and it is clearer to read with the port numbers in ascending order (left to right).

Caveat: no spaces in the comma separated list (just number1,number2,number3,etc).

A variation of this to sort a comma separated list of strings:

sort_css () { echo "${1}" | sed -e "s/,/\n/g"| sort -u | awk '{printf("%s,",$0)} END {printf("\n")}' | sed -e "s/,$//"; }

lsof -nP -c COMMAND | egrep -o '(TCP|UDP).*$' | sort -u

Tags: egrep lsof udp tcp

Where COMMAND is the process(es) name. I prefer to get all states but you may add ESTABLISHED in the grep regex.

lsof -c apache2 | egrep -o 'TCP.*ESTABLISHED.*$'

-nP flags are optional and UDP is irrelevant for established connections

Similar but using the process id:

lsof -nP -p PID | egrep -o '(TCP|UDP).*$'

in this example it counts revisions of current directory.
